dlopen lv2 and sofa plugin modules instead of hardcoding them into the+
filter-chain. This also makes it possible to add more plugin module
types externally.
If we can't find data ports to link, try to find notify/control ports
when making a link.
When applying the link, place the output of the notify as the control
data.
Don't instantiate the graph when negotiated but when starting. This
allows us to get to the target graph rate in case the format rate is
supposed to follow the graph rate.
See #2969
Add ASYNC flag that sets SPA_NODE_FLAG_ASYNC.
This ensure we allocate at least 2 buffers. We need 2 buffers at least
because we don't dequeue/queue a buffer in the process function when
async and we run out of buffers if we have only 1 buffer.
Since UCM doesn't perform the path lookups of alsa-mixer all UCM devices
fall back to the card's properties for e.g. icons and hence usually show
the `audio-card` icon for all ports giving a confusing UI to users as
all ports show the same icon.
As ucm names are pretty standard augment some common port names with
icons.
The old way fails, if a distro has the header but not the library,
which can happen on at least Gentoo with multilib deployments,
where the shared header is present but non-native libraries might not.
This could still fail, if a distro had some but not all libraries for
some architectures but hopefully no one did that. In that case, a compile
test would likely be required via cc.check_header() instead but let's try
the faster fix first.

As far as I can tell, the code in question was not doing anything there
and was also breaking the new code elsewhere, so it was put on the
chopping block. Don't mind the squirming tentacles.

Bring the state to CONFIGURE by actually setting the FORMAT to NULL when
we remove the last mixer. Otherwise the buffers and formats are still on
the port and we might try to use them while negotiating a new format
later.
Avoids some crashes.
Use the port_set_mix_info to add and remove mix info information to the
client.
Previously it was impossible to clean up mix_info.
With this change we can also simplify the jack peer port detection.
Because the mix info is always sent before the link appears we can
simply look up the info when the link appears.
There are currently several issues when multiple alsa devices are
involved.
For alsa devices that are followers, all data is written via
impl_node_process(). Currently spa_alsa_write() is only called if a new
buffer was queued.
It can happen that all buffers are in the ready list (queued by previous
calls but not yet written because there was no free space in the kernel
ring buffer). In this case writing stalls indefinitely.
To fix this, also call spa_alsa_write() if no new buffer is queued but
there are still buffers in the ready list.
If the ready list of the primary device is not empty then only this
device is handled because spa_alsa_write() is called directly. The other
devices make no progress during this interval.
The clock drift calculation works by comparing the alsa delay with the
expected delay since the last wakeup. This only work if the alsa
ringbuffer was filled completly. If the ready list contains a partial
buffer then the ringbuffer is not filled and the timing calculation
during the next wakeup is incorrect.
To fix all this, remove the special case for the non-empty ready list
and just call spa_node_call_ready() every time.
When we don't set a rate, assume both input and output streams are
following the graph rate and so disable the resampler.
This mostly works around an issue where the input and output could
negotiate to different rates in some cases. With the resampler disabled
this would still result in the same amount of samples going in as
comming out instead of a stuttering mismatch.
See #2969
When one side of the loopback suspends, do a EnumFormat params to force
renegotiation on the other side as well.
Suppose this:
1. sink/filter/pw-play plays at 48000Hz
2. pw-play goes away, sink and filter-sink suspend, filter-playback
idles
3. pw-play starts with 44100Hz
4. sink/filter-sink renegotiate to 44100Hz, filter-playback is still
at 48000Hz and pitch shifted.
We might want to manually suspend the IDLE nodes instead but for now
this is a good workaround.
Fixes#2969
There is already an id in the port_mix structure that can be used to
index the mix structures in map if needed, the mix_id is the port_id of
the mixer and should not be confused.
